WILLIAM J. DONNELLEY, or sen FRANCISCO, oALrFonNIA.

STOPPER.

Application filed August 22, 1916.

To all whom it may concern:

Be it known that I. WILL-nut J. Donnnn- LE1, a citizen of the United States, residing in the city and county of San Francisco and State of California. have invented a new and useful Improvement in Stoppers, of which the following is a specification.

My invention relates to stoppers for containers and the like wherein a suitable stopper operates in conjunction with suitable frame; and the objects of my invention are First, to provide an improved stopper that may be easily and tightly secured to a container;

Ficcond, to provide an improved stopper arranged to readily provide accessibility to the container;

Third. to provide an improved stopper secured to the container and yet readily removable as well as easily and permanently secured;

Fourth. to provide an improved stopper having few parts. simple and cheap in construetion and operation and one capable of rendering maximum etliciency.

I accomplish these several features by means of the device disclosed in the drawings forming a part of the present speci1i cation wherein like characters of reference are used to designate similar parts throughout the said specification and drawings. and in which Figure 1 is a side elevation of a container disclosing my invention applied thereto, the dotted lines indicating the position of the stopper when removed from the container.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a broken vertical sectional view of the stopper when in position.

Fig. 4 is a view similar to Fig. 3 but with the stopper slightly raised just previously to being removed away from the mouth of the container, and

Fig. 5 is a broken elevation disclosing a modified form of the invention as applied to a bottle or the like.

Referring to the drawings the numeral 1 is used to designate in general one form of a container having a mouth 2.

A frame 3 is pivotally mounted upon the container 1 as at 1 and is provided with inwardly extending struck up lugs 6 and vertically disposed slots 7 in the sides thereof.

A suitable cup shaped stopper 8 is arranged to engage the mouth 2 of the container 1 and is provided with diametrically Specification of Letters Patent.

opposed integral lugs 9 arranged to slidably engage the slots 7 of the frame 3 and a third integral lug 11 arranged to engage the con tainer 1 near the mouth 2 thereof and thereby aline said stopper 8 with said mouth 2.

The stopper '8 is provided with a suitable cork or other filling in the shape of the washer 12.

ii. threaded stem or screw 14 is rigidly secured to the stopper 8 by means of a nut 16 and said screw or threaded stem 1 1 extends beyond the end of the frame 3 through an aperture 17 provided for that purpose as disclosed in Fig. 4 of the drawings.

A thumb nut 18 is rotatably mounted or screwed upon the stem 14 and rotatably mounted between the struck up lugs 6 and the end of the frame 3 whereby said thumb nut 18 may be retained in position when ro tated and move the stopper 8 away from or onto the mouth 2 of the container 1.

The operation is as follows:

Assuming the stopper to be in the position disclosed in the dotted lines in Fig. 1 of the drawings it will be noted that the mouth 2 of the container 1 is readily accessible for filling or dispensing. In order to close the stopper tightly and effectively upon the mouth 2 of the container 1 the frame 3 is swung to the position indicated in full lines in Fig. 1 of the drawings until the lug 11 engages the side of the container 1 near the mouth 2 thereof thereby alining said stopper 8 directly opposite said mouth 2.

By rotating the thumb nut 18 in the proper direction the stem 14 will move the stopper 8 and the cork or other resilient filling 12 therein tightly against the mouth 2 of the container 1.

To open the container 1 the above operation is reversed.

It is obvious from the foregoing that when the stopper 8 is tightly secured in po sition that it cannot be inadvertently or otherwise removed or loosened without first rotating the thumb nut 18 until the same clears the mouth 2 for the reason that the reaction of the pressure of the stopper 8 against the mouth 2 will press the thumb nut 18 against the top or end of the frame 3 with sufficient pressure to retain the same normally against rotation.

In removing the stopper 8 the thumb nut 18 will be first moved against the inwardly extending lugs 6 which will. serve as an abutment against which said nut 18 may rest while removing or drawing the stopper 8 away from said mouth 2.

By forming the struck up lugs 6 for the retention of the thumb nut 18 I have also provided in a cheap and eflicient manner the slots 7 which are slidably engaged by the diametrically opposed lugs 9 of the stopper 8 whereby said stopper 8 may slidably engage the frame 3.

It is obvious from the foregoing that I have provided an improved stopper for containers and the like that may not only be easily and quickly applied but also one that will effectively secure the stopper against leakage and inadvertent removal as well as a stopper that may be produced cheaply and still possess su'tlicient stability and efficiency.

The details of construction are so susceptible to Variation that I do not Wish to coniine myself to the precise construction disclosed herein but rather to avail myself of any modification that may fall properly within the scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 1. A stopper for containers and the like comprising a suitable frame pivotally mounted upon the container and having struck up lugs and slots therein; a stopper having lugs formed integral therewith, one of said lugs being arranged to aline said stopper with the mouth of the container and the remaining lugs being arranged to slidably engage the slots in the frame; a suitable screw secured to the stopper and extending beyond the end of the frame; and a thumb nut rotatably mounted upon the screw and between the struck up lugs and the end of the frame whereby said stopper may be moved onto or away from the mouth of the container.

2. A stopper for containers and the like comprising a suitable frame pivotally mounted upon the container and having inwardly extending struck up lu s and slots therein; a stopper arranged to engage the mouth of the container and having diametrically opposed lugs arranged to engage the slots in the frame and a third lug arranged to aline said stopper with the mouth of the said container; a threaded stem secured to the stopper and extending beyond the end of the frame; and a thumb nut rotatably mounted between the lugs of the frame and screwed upon the threaded stem whereby the stopper may be moved onto or away from the mouth of the container; the said frame being arranged to move the entire structure in front of or away from the mouth of the container.

In Witness whereof I have hereunto set my signature.
